Im looking into buying one of these printers (RepRapGuru I3 kit). One thing that I've noticed with the DIY i3 printers is that a lot of their power supplies are catching fire, sparking, or smoking... Possibly dangerous stuff. Has that ever been an issue with this printer or is this one safer than the others? / Is the power supply that is used in the kit a reliable power supply or a cheap Chinese knockoff?
